Hello all,
as part of the new direction I am taking with the WRX, I changed out the oil with 300V last weekend.
First observation is that the oil smells sweet like candy.
Second observation is that the use of 300V has reduced engine water temp by 10+ degrees.
I do not have a read on the oil temp, but it stands to reason that the 300V deals with and disperses heat very well.
The water temp with Pennzoil Ultra 5w30 would top out at 204 degrees F with either gridlock traffic or spirited driving.
The water temp with Motul 300V tops out at 192 degrees with the same driving style.
The engine also "feels" better with the 300V. But that is likely a placebo effect of spending $100 on oil!
I will say with confidence however that engine braking does seem to be less noticeable/usable with the 300V. . . .
